Overview

ALTUS Max ICEFill is a product from Lam’s ALTUS family of systems that combines Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) technologies to deposit highly conformal films for advanced tungsten metallization applications. It addresses industry challenges such as minimizing contact resistance and enabling complete, defect-free tungsten fill for nanoscale structures. The product offers benefits such as lower overall resistivity of thin W films, low-fluorine and low-stress W fill for advanced 3D NAND and DRAM, and high step coverage with reduced thickness films by using ALD in the deposition of WN films. It is used for key applications such as tungsten plug and via fill, 3D NAND wordlines, low-stress composite interconnects, and WN barrier for via and contact metallization.
